Add Sprite.AttachTo

[vchelaru]

The following code is how it's done in C#:

Sprite firstSprite = new Sprite();
Sprite secondSprite = new Sprite();
secondSprite.X = 4;
bool keepInSameSpotAfterAttachment = true;
firstSprite.AttachTo(secondSprite, keepInSameSpotAfterAttachment);

In the code above, the two Sprites would be in the same positions before and after attachments, but moving the firstSprite will change the position of the second Sprite.

secondSprite's RelativeX is 0 before the attachment, it becomes 4 after.
